Overview
The LP873200RHDTQ1 is an automotive-grade PMIC from the LP8732 series, featuring dual 2-A buck converters and a low-dropout regulator. It operates within an input voltage range of 2.8 V to 5.5 V. The adjustable output voltage spans from 700 mV to 3.6 V for the switching regulators. The device supports a maximum operating temperature of +125°C and meets AEC-Q100 qualification standards. It utilizes a VQFN-28 package with exposed thermal pad for efficient heat dissipation.
Feature Summary
- Integrates two high-current synchronous buck converters and one LDO in a single compact package.
- Designed specifically for automotive applications with robust reliability and extended temperature ratings.
- Features a wide input voltage range suitable for various vehicle power bus architectures.
Applications
- Automotive infotainment systems requiring multiple regulated voltage rails.
- Digital signal processing units in advanced driver assistance systems (ADAS).
- Telematics control modules needing efficient power conversion.
Procurement Notes
Verify the specific suffix 'DT' against official Texas Instruments documentation to confirm pin compatibility and tape-and-reel specifications. Ensure the component matches the required AEC-Q100 grade for your target automotive application. Cross-reference the datasheet revision date to validate technical parameters before finalizing procurement orders.
Selection Notes
Select this component when designing automotive circuits requiring dual high-current outputs alongside a dedicated LDO. Compare the 2-A current capability against load requirements to ensure adequate headroom. Evaluate the VQFN-28 footprint constraints against available PCB real estate and thermal management capabilities.
Part Context
This part belongs to the LP8732 family of multi-output power management ICs. It shares architectural similarities with other variants like the LP873245RHDRQ1 but differs in specific output configurations and regulatory compliance levels. The family targets complex automotive electronics demanding high integration density.
Replacement Considerations
LP873200RHDRQ1 serves as a direct functional substitute with identical electrical characteristics. Verify package marking differences between the 'D' and 'DR' suffixes to ensure mechanical fitment compatibility on existing boards.
